Where to Buy IGF-1 LR3 in the UK

Buying IGF-1 LR3 in the UK

Buying IGF-1 LR3 in the UK is rarely a question of availability. It is a 83-residue recombinant protein rather than a synthetic peptide, so proper analysis means protein methods, and correct folding is as important as sequence purity.

The suppliers below are ranked on documentation first and price second. Identity-verified companies with batch-matched analysis sit above cheaper listings that publish less, because on this compound the cheaper listing is usually cheaper for a reason.

What to check before ordering

• • Misfolded or aggregated protein is common and cannot be detected by HPLC purity alone.
• • Peptide content stated per 1mg vial, separately from gross weight
• • Batch number on the certificate matches the number on the vial label
• • A batch-matched certificate of analysis (HPLC purity and mass-spec identity).
• • ID verification — we confirm the trading entity behind the website.
• • Independent reviewer feedback on dispatch speed and packaging.
• • Price per mg rather than price per vial.
